The High Level Storage Server is responsible for building structured
multimedia objects and applying an admission control policy to guarantee the
real time requirements of new as well as already being served requests
[admission control reference].
A structured multimedia object consists of a group of monomedia objects along
with a set of constructors to glue them into units, a time frame to
determine the time relationship (temporal synchronization) between the
monomedia objects and a layout to determine the space relationship between
them.
The monomedia objects are those supported by the LLSS: video sequences,
audio clips, still images and text.
